To all whom it may concern:

Be it known, that I, EVERARD HOME MOR- GAN, Va subject of the King of Great Britain and Ireland, residing at 41 BamfordV road,

Didsbury, in the county of Lancaster, England, engineer, have invented certain new and. useful Improvements in Dust-Collectors for Motors -and other Vehicles, of which the following is a specification.

The principal object of this invention is to collect dust raised from roads by the Wheels of motor-vehicles and .to discharge it forthwith in such a Way, and in such condition thatit shall not cause nuisance or inconvenience but tend to improve road surfaces.

Afurther object of this invention is to deodorize the products discharged from the cylinders of motor-vehicles driven byinternal-combustion motors.

According to this invention a motorvehicle driven .by means of an internal combustion motor is provided With pipes, casings or collectors, andfan air ejector or air ejectors in connection therewith by means of which the exhaust products discharged from the internal combustion motor may be made to induce air. to enter into such pipes, casings or collectors, and carry With it dust raised by the wheels from the roads. The said pipes, casings or collectors are connectedto a receptacle or receptacles With partitions or screens or sieves or any other device or devices* enabling dust to be separated from air. The receptacle may be provided with an Archimedean screw or Archimedean screws or spiral or` other conveyer or conveyers or other means for discharging' dust separated from the air continuously.

The products dischar ed from the internal combustion motor in eing used to induce the .current'of air to carry dust into the receptacle or receptacles provided as aforesaid Will be deodorized by mixture lwith the air in the said current land by contact with the dust collected. These products by depositing moisture and other products on the par'- ticles of dust will tend to render them more or less adhesive and so make the dust more capable of remaining Where it may be de# posited than Whenrals'ed by the -Wheels of the motor-vehicle'I and so in course of time to improve the surface of roads by the passage of motor vehicles. l

- In4 any case in Which it may be desirable,

means such iorexample as a pipe may be provided to convey steam or Water vapor from the radiator coolingjacket or vessel fcontaining cooling liquid used with the internal-combustionmotor to the air ejector so that the steamer Water-vapor may be condensed or deposited on the "dust passing through or out of the collecting apparatus in order to aid in-rendering such dust more or less adhesive. y

The bottoni of the receptacle or receptar cles in which the dust Vis separated from the air may be inclined or otherwise and of a semi-circular orother shape as may be convenient to facilitate the discharge ci' the dust .thereiromfby gravity to the ground through a pipe or opening or pipesor openings ccnveniently placed andalways open. Theree ceptacle maybe connected to a container or containers from which the'dust may be allowed to escapel continually by any means such for exampleas openings or conveyors analogous to those already mentioned herein.

In the accompanying drawings in all the iigures of which the saine letters oi reference are employed to indicate corresponding parts, are illustrated by Way of examples some ofthe appliances 'which may be employed in carrying this invention into effect.

In Figures l and Z of the said drawings Whichare respectively a plan and a side elevation, the chassis of a motor-driven-v'ehicle with this invention applied to 'it is shown in so far assis requisite to enable this vinvention and 'its application to motordriven-vehicles to be readily understood and accomplished. l4` 1g. 3 is a horizontal section throng the air-elector or device employed 'in' the apparatus shown as ap lied to the `motor-driven-vehicle illustrater in Figs.y 1 and l? toy enable .the products discharged from the motor to induce currents of air, Fig. 3 being drawn upon a larger scale than Figs. 1 and 2.

il ustrating the construction oi the device used in the apparatus illustrated in l*1 igs. 1 and 2 to allow the air to escape from 'the dust collected. Figs. 5 and 6 are respee tively a longitudinal section and a irnos verse section illustratin(y the applimu' ion ol a spiral conve er to discliarge dust collected by means or apparatus provided according to this invention after separation from the Fig. 4 isa vertical section drawn' u on a larger scale thanlhgs. 1 and 2, and

air used to convey it throu h'such apparatus. Fig. 7 is a side ei evation il ustrating another way somewhat different from that illustrated in Figs. 1 and 2 in which the dust collected by apparatus provided according to this invention `may be separated from the air by means of which it has been conveyed into the said apparatus and be allowed to fall by its own weight from such apparatus. 10 1n Figs. 1. and 2, a are collecting bells at the rear of the wheels b of the motor-drivenvehicle of which part is illustrated in such figures. T he wheels b are indicated diagraml matically in Fig. 1 and only by dotted lines 1 5 in Fig. 2.

The collecting bells a which ordinarily are made to present their openings towards the wheels b respectively adjacent to them although mounted s'o that as will be hereinafter further mentioned, they may be turned aside, are connected by pipes c c to branchpipes d d secured at op osite sides of the casing of an air-ejector e s own as connected by bolts to a cross-rail f secured to the side frames g q of the inetor-driven-vehicle. The

air-ejector c shown is provided with a central nozzle )if secured in one end of the casing 'i of the said air-ejector e and placed in communication 'with the exhaust ipe of the internal-coni risticii-motor so t at the products discharged from the internal-combustion-motor shallA be discharged .through the nozzle h. At the end opposite to that at which the nozzle '/'L is securedthe'casing i', is i, provided with 'a delivery nozzle c formed internally with a passage tapering from the ends 'of the delivery nozzle k towards one part of the interior thereof so that the passage through the said part of the interior of 40 the nozzle lc is smaller than the orifices at the ends. The delivery-nozzle k is made capable of being adjusted lengthwise in the casing t' in order that the discharge through the nozzle 7i. of the products discharged from the internal-combustion-motor may be made most effective in inducing currents of air to flow through the pipes c into the casing i and out through the nozzle 7c and a set-screw Z screwed into the casing i is provided in order that the nozzle 7c may be secured in position when adjusted.

The delivery nozzle k is connected to one end of a pipe 'm connected at its other end to a box n with four arms of which one serves for the attachment of the pipe m, two are provided with openings with. covers o o of wire gauze of a mesh sufficiently fine to prevent dust 0f any importance passing through, while permitting the escape of air or gaseous e0 products and the fourth is connected to a discharge-pipe p provided for the discharge of dustand extending downwards and curved somewhat towards they rear of the motord1iven-vehiels. When the internalcombus- 136 tion-meter of the motor-driven--vehicle is working the products discharged therefrom through the pipe issuing from the nozzle 71 and passing through the delivery-nozzlet1 and along the i e m will induce currents of air to enter the e ls a c yand flow along the pipes c into the casin tof the ejector e and out through the de ivery nozzle k andpipe m to the box 'n from which air and gaseous products may issue through the wire gauze coverings o as well as through thedischarge-pipe 75 p. The currents of air entering the be ls a and flowing through the ipes c to the ejector e and thence througfi the pipe m to the box n will carry with them dust which may be raised by the action of the wheels b in go front of the bells a, a and as the air and gaseous products are discharged principally through the wire-gauze coverings o the dust carried along the pipe m therewith, will with the residue of air and gaseous products be 85. discharged from the box n through the discharge pipe p with but little velocity. 1n passing through the ejector e the dust carried y the air currents enterin the bells a is mixed with the products disc arged from the internal-combustion-motor and is moistened or influenced by the condensation of the water-vapor and other products and thereby made less liable to float in air after issuing from the discharge pipe p thanit was when it entered the bells a and-so when allowed to 4fall from the discharge-pipe p, it will lie or settle uickly upon the road behind the Amotorriven-vehicle and the products discharged from themotor being mixed with the air and dust entering the casing t are deodorized thereby and furthermore smoke in the products issuing from the pipe j is prevented from issuing as smoke from the pipe fm and discharging pipe In the case illustrate in Figs. l and 2 the bells a are mounted to swivel upon the parts by which they are supported and are connected by arms'g to rods r with studs to engage slots in arms s upon a shaft t mounted to oscillate in bearings provided in the frame work of the motor-driven-vehicle and provid ed with a hand lever u by which it may be oscillated to turn the bells a either into the position in which they are shown in Fig. 2 for use or inwards from the position in which they are shown in FigA 2 if it be considered necessary at any time to prevent mud from being thrown into them by the wheels b, a quadrant e carried on one side frame g and a de- 12e tent w carried by the hand lever u being rovided to enable the bells a to be loc-ke in either of the positions into which they may be turned.

In the case illustrated, the sockets in 125 which the bells a a are .mounted to turn are carried in part by the pipes c and in part by stays or brackets p secured to convenient parts of the siderames g of the motordrivenvehicle and brackets z to support and 130 guide the rods i" are provided upon the side frames g, one of the brackets g/ at each side of the vehicle being shown as secured tothe atll jacent side-franies g' by the bolts serving to secure to such side-frame g the adjacent one ofthe brackets y .at the rear of the vehicle.-

Of the brackets y and z only those at one side "of the motor-driyen-vehicle are shown, those l"at the other side being omitted so that-other parts may be better shown.

In the apparatus shown in Figs. 5 and 6, 1 is a box to be carried by a motor-driven vehicle and connected by means of the tiange 2 shown as provided on itto a pipe corresponding to theypipe ym shown in Figs. 1 and 2. The box 1 is provided above with a covering 3, of wire-gauze of a mesh sii'fliciently fine toprevent dust of any importance passing through7 while permitting the escape of 4air and gaseous products` and internally with a spiral-conveyor i made to revolve lby any suitable means as, for example, by a belt or chain applied to a wheel upon it and driven in any suitable way continually while the internal-combustion-motor of the motordriven vehicle is working.

vAt its lower part the box 1 is provided with a. discharge-,pipe or opening 5 and is curved to correspond somewhat to the lower part of the Aconveyer 4 so that such conveyer may be enabledbetter to push to the discharge-pipe or opening 5 dust deposited in 'the box l'after it has been carried thereto bv the current of air induced by means of the products discharged from the internal-com bustion-inotor and the air and gaseous prod ucts from the internal-combustionmotor have escaped from the box 1 through the wire-gauze-covering 3. l

lnllig T is shown a box l corresponding to vand provided at the top with a wire-gauzef covering -3 like the box 1 shown in Figs. 5

and 6 but closed below simply by an inclinedv i surface or inclined surfaces 6 nithe form 45 either of an invertedhollow cone or inverted hollow pyramid and w ith a discharge-pipe l or opening 5 at itslowest point so that dust carried into it by air and gaseous products from an internal-combustion-motor in the manner hereinbefore described being. de-

posited on the inclined 'surface or surfacestV as the air and gaseous products whichhave carried it into thebox l escape through the wire-gauZe-covering 3 may fall "to the discharge-pipe or opening 5 and so be -discharged gently from the box.

'.i'he dotted lines 7 in Figs. 1, 2, and .3, indicate one way in which a pipe connected to the radiator cooling jacketI or vessel containing cooling liquid used with the internal.

ciinbustion-motor may be connected tothe air-ejector r Iso that lsteam or \\'a-ter-vapor lioni the cooling liquid may be led to the airejector to be condensed or deposited on the dust passing through the. pipe in.

example'.

The wire-gauze or other material used in partitions or screens or sleeves or other similar devices for separating dust from air which maybe employed according to this invention must be tine enough to allow air and gaseous products to pass through it but prevent dust of anyimportanee from passing throughr it.

It will be obvious that the pipes or like appliance em iloyed in apparatus provided according to tliis invention may be carried in any positions convenient on the motordriven-vehicles on which they are employed so as not to interfere with the operation of any parts of the mechanism thereof and that when desirable the bells or openings ofthe pipes, casings or collectors employed may be fixed so as to remain in one position relative to the. wheels with which they are used instead of being made capable of being turned aside therefrom.

1t is obvious that instead of an air-ejector such as the air-ejector e illustrated in Figs. l, 2, and 3 of the accompanying drawings,I any other form of apparatus may be employed by means of which the discharge of products from an internal-eoinbustion-iiiotor used in a motor-driven-vehicle may be enabled to induce the flow of air along the pipes, casings, or collectors employed,` in the manner hereinbefore described.

It is obvious that there is such possibility ofvariation in the details of apparatus which may be employed'in carrying this invention into effect that it is only possible herein to describe some forms of apparatus by way of The application of this invention to a niotor-driven-vehicle driven by an internalcoiiibustion-motor enables any dust raised` by the wheels of such vehicle to be caught and collected and put backen to the road so gently and'in such condition by reason of the admixture with it of the products discharged from the internal-combustion-motor that it is able to fall and to remain on the road behind the .motordriven-vehicle, so obviating vthe production of dust-clouds by` the passage of the motor-driven-vehicle along a road and also enables the products discharged from the in ternalcombustion-motor v to be deodorized and prevented from causing any appearance of smoke on issuing into the external air.

If it be thought desirable in any case the ejector or injector or other means by which as hereinbefore described, the products discharged from the interna-l-combustion-motor of a motor-driven vehicle may he made to induce the flow of air through pipes, easings or collectors into a discharge-pipeoi' channel may be employed withoutthe bells or other means hereinbefore described as used to enable dust raised by the wheels of the vehicle to enterth'e pipes, casings or collectors and without the partitionskscreens or sleeves used to separate dust from air as hereilnbefore' described and in such casc the air induced to How along the said pipes, casings or collecs` tors, ln'lixing with the products dischai'gedI from the internal-combnstion-motor will deoderi'z such products and prevent them from causing any appearance of smoke When dischanged into the atmosphere. Furthermore the admixture of air with the exhaust products discharged from the internal combustion motor which takes place in the airejector or air-ejectors employed according to.l this invention cools the exhaustproducts and thereby partially condenses them into Water. In the case of a motor-driven-vehicle driven otherwise than by an internal-combustion-motor or in any case in Which it may not be desirable' to employ the products disf charged from an internal combustion-motor inthe manner hereinbefore described curinternal-combuStien-motors or otherwise and whether made to travel on ordinary roads Aor on rails or tracks of any kind.

The pipes, casings or collectors employed according to this inventionI should be made large in transverse section as may be. permissible for use in the motordriven-vehicles in which they are to be employed and it is particularly important that thc branch-pipes or equivalent parts connectingl the pipes, casings or collectors to the ejector or the place in which the action inducing the flow of air through such pipes casings or collectors occurs shall be larger in transverse section than thc aggregate of the pipes, casings or collectors connected to them, in order that air may pass freely from the said pipes, casings or collectors into such branch-pipes orequivalent parts.

An air-ejector of the dimensions indicated in the case of Fig. 3 by the scale connection with such figure has een found efficient in conjunction with four circular pipes of a diameter ,of one inch anda half.

Having thus described the nature of my said invention and the best means I know provided in of carrying the same 4into practical eect, I claim l 1. In a vehicle driven by an internal combustion engine, the combination of a dust collector having an inlet situated in rear ot livery pipe connected With said ejector and common to all saidcollectors, and a dust se aratin,r 'receptacle connected With said de ivery pipe, with means for' discharging the collected air and dust, substantially as described.

3. In a vehicle driven by an. internal combustion engine, the combination of dust and air collectors with an ejector connected With said collectors and with the exhaust pipe of the engine, a delivery pipe connected With said ejector and common to all said collectors, and a dust se arating receptacle connected With said delivery pipe and rovided with means for discharging the col ected air and dust and for deodorizing said air and products discharged from the exhaust pipe of the engine. I

4. In a motor driven vehicle ,of any type 0 erated by an internal combustion motor,

` t ecombination with an air ejector arranged to receive exhaust products from the said internal combustion motor and to induce the ioW of air through pipes, casings or collectors, of a connection with a radiator cooling jacket of.said motor,'whereby vapor discharged Vfrom said radiator may be led to said air e'ector to be de osited 'on dust carried by t e air passed t rough the said air ejector and to aid said air in deodorizing the exhaust p roducts discharged by the internal combustion motor, substantially as described. 5. In a motor driven vehicle, a pivotally, mounted dust collector with means operable operative and ino crative positions.
